I did the update yesterday on my core and my MD. After killing X I did "apt-get remove nvidia-glx-260", edited out the content of nvidia-installer.sh, downloaded the 285-nvidia drivers from their website and installed them. I did have to struggle a bit, because at first I didn't do it properly and X wouldn't start up again. Actually I had to do it twice, but then it worked and I could get through the AV-Wizard

Hmmm I wonder if it is version or install related. It is a fresh install of 1004. The hardware was working with 1004 (I changed the mainboard and graphics card and after installing the 285 version it was running without problems but I don't know if I ever used the AVWizard). Now with xorg.conf manually set to 1920x1080 I get X but I just cannot get into AVWizard to set up everything properly. AVWizard seems to be using the correct driver:

If you guys would help me, by running this and giving me the output, I will add them to the script to automatically detect these cards correctly.lspci -nn | grep -vi "non-vga" | grep -i vga | sed 's/.*://;s/\].*//'lspci | grep VGA | grep rev
